claims.'

The invention relates to a bailer bottom element and more particularly to a bailer attachment for use in bailing oil or water wells through the use of a pump.

fl' The primary object of the invention is the provision of an element of this character wherein the bailer tube carries a tr-ap and this trap is in the form of a valve having sections, these being so arranged for taking care of expansion and l@ contraction and also to assure proper seating for the sustaining of a load in the bailing operation.

Another object of the invention is the provision of an element of this character wherein the bailer can be readily opened or closed and when opened permits dumping or unloading of the substance pumped during the drilling operati-on in the drilling of oil or water wells.

A further object of the invention is the provision of an element of this character wherein the trap is of novel construction and is susceptible of proper seating for the sustaining of a load and also enables the fitting thereof to ldifferent sizes of bailers.

A still further object of the invention is the provision of an element of this character which is simple in its construction, thoroughly reliable and ecient in operation, readily and easily assembled, possessed of few parts, being strong, durable, and inexpensive to manufacture and install.

vention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described in detail, illustrated in the accompanying drawing, which discloses the preferred and modified forms of the embodiment of the invention and pointed out in the claims hereunto appended.

n the accompanying drawing: Figure l is a vertical longitudinal sectional View through a bailer bottom element constructed in accordance with the invention.

Figure 2 is a sectional view on the line 2 2 of Figure l looking in the direction of the arrows.

Figure 3 is a sectional view on the line 3 3 of Figure l looking in the direction of the arrows.

Figure a is a top plan View partly in section of the modified form of trap,

Referring to the drawing in detail, particularly Figures l to 3 inclusive, A designates generally the bailer bottom element in its entirety and comprises a tubular body l0 constituting a bucket being of substantially uniform cross sectional internal diameter and has integral therewith at its lower end a shoe l l the external diameter of which is slightly greater than the external diam- With these and other objects in view, the in-v (Cl. 16S-19) eter of the said bucket body l 9 to effect an external shoulder l 2 with relation to said bucket body. Rotatably lit/ted about the body i@ is a sleeve like shutter or gate i3 having therein at diametrically l opposite points discharge openings i4, these-1'5" adapted to register with diametrically opposed companion discharge openings l5 in the said body it and when such openings are in register the bucket body can be emptied or dumped. rThe shutter or gate i3 is normally turned so that the '10 openings lli therein will be out of register with the openings l5 in the bucket body l0 for the loading thereof in the usual well known manner during hailing operation with the useof the bottom element. I1li The shutter or gate i3 has Contact with the shoulder i2 and is Xedly and rotatably held on the said body l through the use of superposed jam or lock nuts l5 threaded at l 'l on the body l d, these nuts being provided with wrench sockets i8 for manipulation thereof.

Arranged within the bore l 9 in the shoe l l is a sectional self-adjusting dapper valve or valves forming a trap which involves an intermediate section 2@ and adjustable outer sections 2l, respectively. The said sections 2E are loosely connected to intermediate section 20 to form a freely extensible and retractible iiapper valve structure. The sections 2U and 2l are upwardly arched and the said intermediate section 2b is joined with a pivot arm 22 swingable on a pivot 23 tting the said shoe, the latter being formed with a clearance 2t for the swing of the apper or trap in a Vertical direction, 'Ihe intermediate section 20 is formed with elongated slots 25 arranged at the transverse median of said flapper or trap and accommodates adjustable fasteners 2S which are engaged in the outer sections 2l and in this manner the latter are susceptible of adjustment relative to the section 2? for the proper iitting and seating of the flapper or trap in the shoe.

Tapped into the shoe ll remote from the pivot 23 or diametrically opposite the same is an adjustable seating plug or stop lug 2l engagable by the apper or trap to maintain it in a closed position within the bore i9, in said shoe so as to have a load of substance retained in the bucket body l@ in the operation of the bailer. The body l0 is attachable to a suitable tube, not shown, usable for hailing and such tube is associated with suitable 1nailing tackle, not shown.

In Figure 4 of the drawing there is shown a modiiied form of flapper or trap which involves leaf hinge sections 28 these formed with pintle eyes or hinge pivot sleeves 29 for a pintle or hinge pivot 3l! having a terminal 3| for swingable mounting of the flapper or trap corresponding to the one involving the sections 29 and 2| hereinafter set forth. FiXedly disposed crosswise of the pintle or pivot 30 is a rest 32 for the sections 28 which are upwardly arched and are vertically swingable to and away from rest position on the rest 32 by the pintle or pivot 30. The last described flapper or trap is a substitute for that construction of flapper or trap first mentioned heretofore.

The preferred and modified forms of the flapper or trap hereinbefore set forth are designed to handle thinner substances in the bailer and to conform to the shape of the bottom element With assurance of a closer seal in the closing position and a larger opening in an open position with respect to said flapper or trap, as Well as allowing for expansion and contraction of such lapper in the assembly thereof, as Well as in the conformity with the internal bore of the shoe I l of the bottom element.

The arched formation of the trap is such that when the latter is in an open position it conforms to the curvature of the cross sectional diameter of the body I0 of the bottom element.

What is claimed is:

1. A bailer bottom element comprising a perforated tub-ular body having a cylindrical shoe at one end and provided With an external annular shoulder below its perforation, a perforated sleevelike gate movable externally about said body for registering its perforations with the perforation in the said body and resting upon said shoulder, lock nuts exteriorly about said body and operable to lock said gate in desired position, and a movable trap comprising loosely connected sections arranged Within the shoe below the perforation in the tubular body.

`2. A bailer bottom element comprising a tubular body having a side opening therein, means on the body for opening and closing said side opening, and a trap swingably supported in said body below the side opening and including a plurality of arched separate sections loosely adjustably connected together.

3. A bailer bottom element comprising a tubular body having a side opening therein, means on the body for opening and closing said side opening, a trap swingably supported in said body below the side opening and including a plurality of arched separate sections loosely adjustably connected together, and a stop xed in said body for said trap and holding the latter seated When in a closed position.

4. A bailer bottom element comprising a tubular body having a side opening therein, means on the body for opening and closing said side opening, a trap swingably supported in said body below the side opening and including a plurality of arched separate sections loosely adjustably connected together, a stop iXed in said body for said trap and holding the latter seated when in a closed position, and means for loosely fastening the sections of the trap together.

5. A bailer bottom element comprising a tubular body having a side opening therein, means on the body for opening and closing said side opening, a trap swingably supported in said body beloW the side opening and including a plurality of arched separate sections loosely adjustably connected together, a stop iixed in said body for said trap and holding the latter seated when in a closed position, means for loosely fastening the sections of the trap together, and a shoe formed with said body and receiving the said trap.
